What do Jessie Mach, Michael Knight and Stringfellow Hawke have in common? They were characters played by Rex Smith, David Hasselhoff and Jan-Michael Vincent in Street Hawk, Knight Rider and Airwolf respectively. These three shows filmed in the 1980s were probably among the most exciting action adventure serials ever aired on television.

While all 3 shows (with very catchy theme tunes) were exciting Airwolf was unique in that it added an aerial element to the whole concept of a high tech crime fighting machine. It featured a state of the art helicopter fitted with high tech weapons and gadgets and capable of supersonic speeds. It was also the show that first got me interested in helicopters and made me decide that I would one day get a helicopter pilots license (until of course I grew up and mortgage concerns got in the way..darn). This post as you would have guessed by now is about the helicopter.

Here is a brief history of the chopper. Around 2000 years ago some bored Chinese bloke (apparently called Ko Hung) who didnt have shows like Airwolf to keep himself entertained (and no girlfriend either) decided to attach some feathers around a stick to create a flying toy. Hung found out that when he rapidly spun the toy in his hands and let it go it would rise vertically and fly by itself for a few seconds. Overjoyed by his new invention he proudly displayed it to his mates who all thought it was totally cool. This became the Play Station 2 of their generation and came to be called the Chinese Flying Top.

Over the years that followed several people around the world envisaged a larger flying machine based on the principles of the chinese flying top. In the 15th century Leonardo Da Vinci studied the possibility of a human carrying helicopter. The word helicopter is derived from the Greek words helix (spiral) and pteron (wing). However it was not until the invention of the internal combustion engine and the advent of powered fixed wing flight that actual helicopter models were produced.

Unlike the Wright Brother's first flight there is no specific date or inventor to whom the first flight of the helicopter can be credited. However a Frenchman named Paul Cornu is credited with the first piloted rotary wing flight in 1907 when he reached a staggering altitude of 1 ft with his twin rotor craft. The long history of development of rotary wing flying machines around the world which eventually led to the modern helicopter is too detailed to go into in a simple blog post (and also too boring). I will however mention Igor Sikorsky who is credited with building the world's first practical helicopter the Vought-Sikorsky 300 in 1939.

Here is a little bit about how a helicopter flies. A conventional fixed wing aircraft flies due to the lift generated by the wings. A rotary wing aircraft or helicopter is not that dissimilar. Each blade of a helicopter is effectively a wing that generates lift as it goes around. However as the main rotor blades spin and generate lift they tend to spin the body of the helicopter in the opposite direction and hence the need for a tail rotor to compensate and provide yaw control. There are helicopters that use 2 sets of rotor blades each moving in opposite directions to cancel out the spin so they do not require tail rotors. There are also NOTAR (no tail rotor) helicopters that use a jet of air to provide yaw control and stability instead of a tail rotor.

Most modern helicopters use gas turbine or jet engines (from the Bell Jet Ranger to the Apache attack helicopter). Most people think jet engines are only fitted to aircraft but in addition to solely producing thrust to power an aircraft they can also be converted to use most of that power to drive propellers or rotors (turbo-shaft and turbo-prop engines).

The helicopter probably has more uses than any other flying machine ever invented. It is used for search and rescue, transport, sightseeing, fire fighting, traffic monitoring, news reporting, police surviellance, troop support, Medevac..the list is almost endless.

Here are some interesting helicopter facts:

1. The Fastest

The world speed record for a helicopter stands at 249.1 mph. This was set in 1986 in the United Kingdom by a modified British Army Westland Lynx helicopter. The helicopter neither looks fast nor does the speed seem all that high. A helicopter's forward speed is severely limited due to the increased stress on the blades at high speeds. As the forward speed of a helicopter increases the rotor blades start approaching supersonic velocities. At this point the stress and vibration levels and the power requirements drastically increase making any further speed increases difficult and dangerous (at least with current design and materials).

2. The Biggest

The Mil Mi-26 "Halo" is currently the biggest helicopter in the world. Built and first flown in 1977 by the Mil helicopter company in Russia this helicopter is currently used in military transport, fire fighter and medevac roles.


3. The Deadliest

The Boeing AH-64 Apache attack helicopter and the Boeing-Sikorsky RAH-66 Comanche stealth helicopter are probably the closest real world equivalents of Airwolf and Blue Thunder (although the Comanche project has now been cancelled).



4. The Hybrids

The Bell-Boeing V22 Osprey tilt rotor is an example of a helicopter/aeroplane hybrid which takes off like a conventional helicopter and tilts the rotors forwards to fly like an aeroplane once in the air. Another unusual flying machine was the large Fairey Rotodyne which was a cross between an autogyro and a helicopter.

and finally......

5. Airwolf & Blue Thunder

A modified Bell 222 helicopter was used for the popular Airwolf TV series. Once the series ended the modifications were removed and the helicopter was sold to a German charter company. It crashed in the early 90s killing all on board.

2 modified Aerospatiale Gazelle helicopters were used for the Blue Thunder movie and TV series. After the Blue Thunder series ended one was sold to a salvage company and the other was sent to a hollywood museum somewhere in the States.

There ends my little story of the helicopter. Hope you enjoyed reading it.

Nice post. :-)

I was hoping that you would mention the Lockheed Cheyenne - another potent chopper with a pusher propeller. And of course the Kamov Ka-26, Ka-31, Ka-50 and Ka-52 all work on that age old concept of contra rotating propellers. As for the deadly ones: The Ka-50 Hokum and the Mi-28 Havoc are pretty deadly as well, not to forget the Mi-35 Hind.

Other "hybrids" are are the XV-15, the Ryan X-22, the XC-142 and other experimental machines which really led to the Osprey.

I visited a helicopter museum in a place called Weston-Super-Mare in Somerset sometime ago. They claimed it was the largest dedicated helicopter museum in the world (I found that hard to believe as it didnt look much bigger than an avg sized hangar).

Anyway they had the Lynx ZB500 (the one that set the speed record). They also had a Mi-24D Hind and I thought it looked quite scary even by just sitting there in the hangar.

In case anyone is wondering what the Hind looks like it was in one of the Rambo movies (the one where mr incredible takes on the entire Russian army, airforce, afghans, terrorists and some random people all thrown in for good measure).

hye, nice info on Airwolf and Bluethunder. I agree its the best damn action series ever. Miss it so much. Sometimes they air it during the retro season reviews. I still remember the episode when a double airwolf appeared, the red colored nemesis.

Nice info.

Great blog you got here. I'd like to read a bit more concerning this matter. The only thing that blog misses is a few pictures of some devices.

My father retrofitted and flew the Blue Thunder (TV) ships (we had a jet black gazelle that served as one of the two airframes) and the Russian Hinds in Red Dawn (we 3 borrowed Pumas) and Rambo (built on our our fleet S-62 Airframe). That's also us in the Jet Ranger camera ship at Blue Thunder's 2:00 in the pic.
